What Does Creatine Do: Expert Guide

Most supplements promise energy. Creatine is one of the few that explains energy in a way your body actually recognizes—because it works with the same “instant battery” system your muscles already use when you sprint, lift, jump, or grind through a tough set. The funny part? People often start creatine for “bigger lifts,” then stay on it because training feels more consistent: fewer flat days, better repeat performance, and less of that “I’m gassed way too early” frustration.
